A man convicted of manslaughter is now accused of fatally shooting two people Sunday in a central Phoenix apartment building, police said.

Cleophus E. Cooksey Jr., 35, was arrested on suspicion of first-degree murder and possession of a weapon by a prohibited person, officials from the Phoenix Police Department said Monday.

Officers found Cooksey in an apartment with two deceased people just before 8 p.m. near Highland Avenue and 12th Street, officials said. Someone called 911 about hearing gunshots.

Both of the deceased had been shot. Officials said their names will be released after next of kin have been notified.

Arizona Department of Corrections records show Cooksey previously served 16 years in prison for manslaughter and armed robbery convictions. He was released in July 2017 after being found guilty of 22 different disciplinary infractions while in prison, including assault of prison staff, disobeying orders, fighting, disorderly conduct, possession of drugs and more, according to the Corrections website. Those infractions spanned from 2002 to 2017, records show.
